Fix mysql authentication errors

The mysql-server package on Ubuntu16.04 was recently updated to disallow
unauthenticated root user login over tcp/ip.  This, coupled with pymysql
using tcp/ip whenever host and port is specified causes us to fail to
connect to the database when testing Python3 on Ubuntu16.04.

The fix is to use the unix socket instead.
